Mac: The new MacBook Pro with a retina display are great to look at, but not every piece of software has been updated to support the higher resolution. Retinizer is an app that allows you to force higher resolutions in apps where it's possible.

Right now, Retinizer works with a handful of apps, including Microsoft Office, and a few others. It doesn't work with Adobe Creative Suite, or any Adobe Air apps. Still, the process to upgrade your apps is simple. Just drag the app into the Retinizer window, click "Retinize!" and you're done. Check out the developers site for the compatible apps, and a free download of Retinizer.
